In this paper, we present a design method of 2-Dimensional (2D) linear phase (LP) perfect reconstruction (PR) FIR filter banks based on Lagrange multiplier method. In M analysis filters, we first design M-1 analysis filters suitably which have LP property. Finally we design Mth analysis filter with LP so that the overall system satisfy PR. Then Mth analysis filter is optimized to have good response while keeping PR based on Lagrange multiplier method. By this method, 2D LP PR filter banks can be easily designed by only solving the simultaneous equation, although the order of Mth analysis filter is higher than that of others.
